Three, the bubbles volume during high pressure gas knows from experience liquid such as increasing electroplate liquid, is so sprayed onto the uniformity on the objects such as circuit board by liquid such as having influence on electroplate liquid, has a strong impact on the processing quality of the aspects such as plating.
Four, the composition such as the oxygen in gases at high pressure can produce reaction with the some chemical properties in the industrial chemical medicinal liquid such as electroplate liquid, lead to the industrial chemical medicinal liquid accelerated deteriorations such as electroplate liquid, reduce the service life of the industrial chemical medicinal liquids such as electroplate liquid, dealer changes the frequency of the industrial chemical medicinal liquids such as electroplate liquid and raises, the acquisition expenses increasing the industrial chemical medicinal liquids such as electroplate liquid and the expense disposed waste liquid.
